IMPROVEMENT IN WATER-ELEVATO RS.

Specification forming part of Letters Patent No. 40, |19, dated September 29, 1863.

To all whom it may concern Be it known that I, ISAAC A. PINNELL, of Galva, in the county of Henry and State of Illinois, have invented a new and Improved Water-Elevator; and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanying drawings, forming a part of this specitieation, iu which- Figure l represents a side elevation of my invention. Fig. 2 is a longitudinal vertical section of the same.

Similar letters of reference in both views indicate corresponding parts.

The object of this invention is an improvement in that class of machines which are generally used to facilitate and regulate the operation of raising and lowering well-buckets.

The invention will be readily understood fi om the following description A represents a drum, of wood or any other suitable material, which has its bearings in suitable boxes on the top of the well-curb B. The shaft a of the drum extends beyond the on the side of the curb, and secured to its box end is a toothed wheel, C. This wheel gears into the internal teeth of a large wheel, D,

which is secured to the end of a short arbor, b, having its bearings in suitable boxes on the top edge of the curb. The wheel D is provided with a handle or crank, e, so that it can be rotated 'with ease and facility, and a pawl, d, which catches into the teeth of said wheel, prevents it being moved in the wrong direction.

E is a hand-lever, which has its fulcrum on a pivot, e, and the forked end of which catches over the drum-shaft a, near to the toothed wheel C. The journal of this shaft, near that end which bears the toothed wheel, is so arranged that it can be moved towardand from the center of the wheel D, and by depressing the hand-lever E the wheel C moves toward the center of the wheel D, and it is thrown out of gear with said wheel. A spring, f, which is secured to one of the uprights of the curb and bears against the forked end of the lever E, has a tendency to keep the wheel C in gear with the wheel D, and whenever the hand-lever E has been depressed and is released, the wheel C is immediately thrown back in gear with the wheel D by the action 0f said spring.

F is a curved spring, which is secured to the top of the curb, and which is bent over the ange of the drum A. If the wheel C is in gear with the wheel D the spring F does not touch the periphery of the iiange, and this drum rotates quite freely and without obstruction; but when the wheel O is moved toward the center of the wheel D, the circumference ofthe iiange bears against the spring F and said spring acts as a brake.

The bucket in which the water is to be elevated is suspended from a rope or chain, which winds on the drum, if the wheel D is rotated in the direction of the arrow marked upon it in Fig. l, causing the drum to rotate in the direction of the arrow marked thereon in Fig. 2, provided the wheel C is in gear with the wheel D. If the handle of the wheel D is released, the drum A is prevented from rotating in a backward direction by the pawl d, which arrests the motion of the wheel D in the wrong direction, and the bucket re- Inains suspended in whatever position it may happen to be.

It it isv desired to lower the buckets, the wheel C is thrown out of gear with the wheel D by depressing the hand-lever E, and the drum being now free to rotate in the direction opposite to the arrow marked upon it in Fig. 2, the velocit-y of the descending bucket is checked and regulated by the action of the spring j', which bears upon the periphery of the wheel C and acts as a brake. The pressure of this brake upon the wheel G is regulated by the force exerted in depressing the handlever E, so that the harder the hand-lever is depressed the more powerful the brake will be applied.

When the bucket is raised, a hook projecting from its edge catches under a bail hinged to the inside of the curb, and causes the bucket to discharge automatically.

What I claim as new, and desire to secure by Letters Patent, is-

Ihe forked hand-lever E and brake f, in combination with the d rum A and wheels C and D, constructed and operating in the manner and for the purpose herein shown and described.
